Lpplinatlonfilod May 8,1905- To all whom it may concern:

Be it known that I, Ron'mrr ZmLLnn, a subject of the Kin of Bavaria,residin at Munioh,Kingdomo Bavaria, Empire of or meny', and te'mpororiiires! v Furnaces, of which the following is a. specification.

The present invention relates to smokef "eons f furnaces; and itconsists of the construction hereinafter setiorth, and perticularlypointed out in the claims.

The water oil-cull I i the new; e-teippereture tribes preventsthe mel of t P nd also m ts s re.

Thedownward assages n, oonimunioatin the channe m, are preferably narrowsottbe bottom, so as to form nozzles. a

The transverse channels Z m be closed bit plugs, preferably of fireproofmaterial, whic plugs may durm the operation of the fur name be crnshed ybeing pushed inwardly b means of an iron rod, thus openingthe 1c snnelsy In addition to the bafller I provide at the upper part of the fireboxa series of arches H, so arranged as to prevent the passage of smokebelow the boiler and above the beflier. When the furnace is as broadone, it is preferable to strengthen these arches by inserting thereiniron supports. I refer to construct these in the form of tubes lprovided at intervals with apertures on the iower portions thereof, so 7that air or other substances furthering combustion or combustiblemateriel insv be introduced 'therethroo h into the firebox.- The brickscomposing t e arches may be open at one side, as shown in Fig. 1, so asto permit 'th'e'huiiding of the arch when the tube is already in placeand also to permit the air or other material esoe iog from the a erturesin the tube to escape V ownwardl he bricks may be iaid with the open ngsextend ng olternatin 1y downwardl and sidewise, as shown in ig. 1. Theseshes are connected with the exterior ofv the furnace by a channelpassing thro h the well of the furnace. (Not shows 111 the rawings.) H

The operation of my device is as follows:

After the fire has been -sta,-rted in the fire-box the draft is mostintense inst below the baffier, as all or the, majority of the productsof combustion have to pass between the baflie'r and the coal resting onthe grate The zone of most intense combustion therofore,-- is just belowthe bafier, end the temperatereio this zone is suflicient absoiutely tooxidize all the combustible residues of imperfect combustion; AH thegas, smoke, particles of cool,

and other residues of imperfect combustion usually thrown out of thechimnep) are thereburned, thus 0 taining. e mcximumemount of heat fromthe coal and emnittiog no noxious gases, smoke or cool-- set toosoesdthe chimney". increase the combustion at what 1 term th zone ofmost intense combustion, air, liquid fuel, orother ozudming' or con'ibusIn order to use air or other oxidizing innterinl introdnqed 7 into thefire-Jung through the pipes Iund ehitn' nel F. .Shmlld-nt any time thegages in t he i ten of the fire-hm heeolne stngn mt,eneor more of theSIiHLll; ehennels l may re opened by removing or eriishing the plugs Gnegle- Zserihed 'thusi ier' n itting the escape of the zq' -git eg tithese channels are at a red heat, theite npereture beingnhowet-hitnecessary for thg 'eommete-eon]hustion of the gases, coahdus -t nnrl"Sn-nuke, and therefore all .of these s21ili;strn ees. 2 5
